We discovered Box Fresh Organics at a food fair, they deliver fresh fruit and vegetables to your door, you can have any sized box delivered, when you require it, and if can either be a box of veg or just a box of fruit, it's down to what ever you require.
We have a veg box delivered every 2 weeks, we've only been on the scheme for just over 2 months now, and every box we've had contains a varierty of veg, which is always fresh. You are guareented potatoes, carrots and onions as standard, then the rest of the box is filled with what ever is in season. If there is something you dont like, just let them know and they wont send it to you again.
They will also provide other organic products like eggs, meat, oil, juice and flour, so we also have free range eggs delivered.
I would recommend this company, it's easy and convient, they deliver straight to your door, and you can pay by direct debit each month, I would rather pay a local company for fresh, organic produce than using the supermaket.
